Stan's NoTubesReplacement Presta Valve Core (5-Pack)(Return to Product Page)

You can buy cheaper valve cores, but these appear to be better quality than the low bidder stuff. I've had several valve cores just bend or come apart without being abused. So far these have not failed. I suspect the materials are better than the El Cheapo alternatives. Maybe you get what you pay for with this product.

Price and quality! Good

Seems simple to have the valve stem working. With most running tubeless tires the valve stem can get sealant in it. It can create a problem with stem either not closing fully or getting stuck. A clean valve stem is a wise proactive maintenance detail. It's inexpensive and can save a headache out on the road or trail.

First time buying valves. They fit right and are easy to install.

I purchased these knowing that they would get used. I replaced a tire and decided to put in a new core. I was very happy that I did. Works great and is worry free.
